[Android Q&A, Help & Troubleshooting] Maine_Coon:
there is file bootanimation.zip in the /system/media folder.

I renamed it to bootanimation.old and put in my own.

No effect.

Yes, there is a difference between initial startup screen and boot animation.

If you look closely you'll see changing colors on V logo.
[Android Q&A, Help & Troubleshooting] mlewis2388:
Yeah I found that file too but it truly doesn't do anything. There isn't even a bootanimation that works, it's a single file under framework-res.apk (in the images folder). I can't remember the exact name but it's called something like vlogo.png. I changed mine and got it working.

Ok I'm a little confused and not an super advanced android user. I've rooted a couple of phones and flashed roms etc.. Is the CWM for the Vtab1008 fully functional? Can I create an nandroid backup of the entire system? I read in the OP that it does not backup kernals and ramdisks. I suppose all I really want to know is can I backup my system and restore it if I screw up a customization etc?
[Android Q&A, Help & Troubleshooting] tselling:
Is there an image of the 1.4 system that I can flash with CWM? My refurb vtab1008 came with 1.2 and it wants to update to 1.5 but I haven't let it. I want to update to 1.4 and trying to figure out if there is a way to do that. Thanks.
[Android Q&A, Help & Troubleshooting] FadeFx:
Hi, you can do your customizations, it does backup all partitions, but can not restore kernel and ramdisk. Only other thing i found is that the edify mount command is not working and causes problems in scripts, but there is a workarround to that.

@rprr can you modify op to show that as a known problem as well?

Too late I was playing around before installing and backing up. I bricked it was hoping someone had a rom I could flash an update. I bought off. Woot so I emailed Vizio support telling them it arrived like that. Probably a shady thing to do. I think

Should have cwm first I have no idea what I was thinking. I have another that's not rooted if there's a way to back it up and transfer?

[Android Q&A, Help & Troubleshooting] FadeFx:
So u got no cwm now you could flash a rom from? If u have i could send you a backup of my system partition, but you definitely need cwm to flash anything.

[Android Q&A, Help & Troubleshooting] dms76:
Yeah I think I am kinda screwed! Oh well serious lack of judgment on my part to play around without a backup. Recovery mode gives you options to flash from SD card. I don't think I can do that because don't you need the private keys to generate an update.zip that the phone will accept?

Edit: Phone = Tablet!

Thanks. I have modified the OP.
[Android Q&A, Help & Troubleshooting] tselling:
I thought I would try to help this effort by downloading the 1.5 update and finding the zip file. I think I have it. An update.zip file from /cache/ULI. Its 123mb so I can't just attach it here. I will post a link once I get it uploaded somewhere.

Do you think I can safely delete it from the /cache/ULI directory before rebooting so it doesn't get installed? Also maybe someone with version 1.4 can check /cache/ULI to see if they have an update.zip file and can send it to me since I only have 1.2 installed and would like to update to 1.4 (course the file may get deleted once installed).

There was also a uli.txt file in the /cache/ULI directory whose contents were "Please don't erase this file!" without the quotes.

The update.zip file should hopefully be here: http://www.4shared.com/file/XakOT7gS/update.html

EDIT:

I also found a couple of possibly related files in /ULI/uli_rwd

-rw-rw-rw- app_0 app_0 8040 2011-12-19 10:57 persistent-storage.dat

[Android Q&A, Help & Troubleshooting] rprr:
Good work. It does appear to get deleted once installed. Have you installed CWM recovery? If so there may be a way to take an existing system backup and reinstall. I will see if there is an easy way to do this.

How did you stop the download from installing?
[Android Q&A, Help & Troubleshooting] tselling:
I haven't rebooted. I figured that it wouldn't be installed until the reboot. I am guessing if I delete the files then it won't install, but I haven't tried it yet.

I do have CWM installed but I haven't done anything with it other than see that it does come up during recovery.
[Android Q&A, Help & Troubleshooting] SilverPony2001:
Checked /cache/ULI and all I have is the uli.txt file. My Vtab came with 1.4 installed though, I never had to update to 1.4 so maybe someone that updated to 1.4 has a zip.
[Android Q&A, Help & Troubleshooting] tselling:
I deleted the update.zip and then clicked ok to allow the reboot and I got a message saying the system deleted update.zip and to please use update manager to redownload or something to that effect... so I will refreeze the update service until we get more figured out. I am hoping we can just modify the update.zip to allow rooting or maybe even build in root access but I am not sure what is involved.
[Android Q&A, Help & Troubleshooting] rprr:
Unfortunately, the zip gets deleted once updated :(
[Android Q&A, Help & Troubleshooting] FadeFx:
Id suggest to build an update.zip based on your update.zip file but i need to take a look at your file first. Possibly we can change it so we can have the system updated without loosing rooting ability.

Regarding your current firmware version, you could just take a nandroid backup from an other vtab and restore /system partition and possibly dd the kernel to kernel partition. Will see if i can make a update.zip for you. Only problem is, i wont find time before tuesday...

I downloaded and installed this update and restored my bricked vtab.

I lost root but it's better then a bricked tablet that's fore sure! It's a little weird because it says software version is V.I.A. Plus 1.4 and Build 1.9.57.

If there is anything I can help test for 1.5 root let me know!

[Android Q&A, Help & Troubleshooting] FadeFx:
I think we could just remove the *.img files from the update.zip, this way it should be possible to get all the new apks and libs, flash the update from stock recovery as the signed updater script has not changed, and possibly even add the needed files for root (su binary, superuser.apk and latest busybox) possibly we could leave the zimage.img file there as well, as i think the file that blocks root is located in the ramdisk.img.

But i don't really want to suggest to try that as of yet, rprr should have a look at this first too, i think he can open the .img files on his Linux or macos machine and have a look at it. I guess we need to s-off this...

[Android Q&A, Help & Troubleshooting] FadeFx:
Can u repack it with a modified default.prop changing ro.secure=0?

This is what blocks write access.

Ok, ro.secure = 1 is set on rooted firmware as well, so it must be something different. Possibly the bootloader has changed. Is there a way to compare?

--------------------------

tapatalked from vizio vtab1008
[Android Q&A, Help & Troubleshooting] rprr:
I believe that the main change that blocks the root exploit from succeeding is the /system/lib/libsysutils.so. The exploit zergRush uses an ASLR loophole in the libsysutils.so. However, it is possible that all the other apps have been recompiled against this new libsysutils.so.

I am also listing all the differences between the two system folders.
[Android Q&A, Help & Troubleshooting] dylanparrish:

[Android Q&A, Help & Troubleshooting] rprr:
I also believe that just repacking it is not enough to push with the default recovery. It will fail signature verification. Please also check the updater-script. There will be no need to flash u-boot.bin, ramdisk, zImage etc. To me it appears that they are all identical.
[Android Q&A, Help & Troubleshooting] rprr:
I have copied the updater-script below.

As you can see it over writes the /system, /kernel, /ramdisk, /sm0, and /misc (which contains u-boot).
[Android Q&A, Help & Troubleshooting] FadeFx:
Hmm, i am not sitemap but i think if you replace the files in the existing zip it wont be needed to resign afaik only thing signed is the updater-script and possibly the update-binary

Thanks for posting the official 1.5 update. I downloaded it, just in case.

So with the CWM mod, which I've been hesitant to install, I can back up my system directory and restore, should there be some problem in the future. Is this correct? Will it still be able to load the official Vizio updates, should something we all want actually come out?

I'm not that good at adb and I need some help. I flashed the CWM port about a month ago. Today my screen started to get fuzzy looking. I want to flash the stock recovery and send it in for repairs. I downloaded the original recovery from post #9. I pushed to the sd card using this command adb push receovery-orig.img /sdcard/recovery-orig.img It looks as though it pushed fine. then I entered adb shell and su and then I did this command dd if=/sdcard/recovery-orig.img of=/dev/block/mmcblk0p5 bs=512. Now it appears that I don't have any recovery. When I try to enter recovery my tablet bootloops until I let go of the volume button then it boots up normal but no recovery. Any thoughts?

A success story

I bought a VTAB around Thanksgiving and immediately rooted it using rprr's guide. I found a few days later that the unit had a bad SD card reader (card wasn't making contact to the internal reader when inserted, but would work with enough pressure), so I contacted Vizio for a warranty replacement unit. It took almost 6 weeks to go through their "Advanced Replacement" process, which was originally quoted to take 5-7 business days. During the waiting time, I was able to use rprr's CWM guide to install CWM & make a complete backup of the faulty tablet unit, since I had spent some time setting it up. When the replacement tablet finally arrived, I was relieved to find it had not had the VIA 1.5 update, so I was able to quickly root the new unit with DooMLoRD's v4 kit, install CWM and restore the system to match the old/faulty unit. The only issue I ran into was DooMLoRD's adb.exe could not see the VTAB. I had to copy over the adb.exe from my DroidExplorer install for the batch file to work. Now I have a working VTAB set up just the way I like it and a working SD card reader!

A BIG thanks to rprr & DooMLoRD for their parts in saving me lots of time and headache.

Can't back up?

I followed the instructions in the top post after rooting my device... I was able to get CWM installed and reboot into it, but when I try to use Nandroid it tells me "Can't mount backup path" ... is this normal for everyone or is something wrong with my unit?

[Android Q&A, Help & Troubleshooting] FalconFour:
Back on the first page, rprr posted a mmls dump from "mmcblk0.img"... which has been the most valuable post I've seen so far in this thread for my situation.

I had CWM recovery installed, then in a leap of faith and some crafty hacking, I utilized CWM's "disable signature validation" hack to modify the update, inject "su" and related rooting components, and apply the 1.5 update. I read over the installer script and saw what it was doing - re-imaging some system partition, etc. - and figured it was worth a try.

Nope. Bricked. It does nothing now... no screen, and only the orange LED lights up when USB is plugged in (but doesn't come up as a device - nothing detected). Crap.

Well, I later read some horror stories about "bricked mine too... damn", and it seems like everyone just gives up on it somehow (really? jeez, disposable society). But I couldn't imagine they'd design this thing without some fail-safe measure, like booting from the external SD like the Nook evidently does when it's bricked.

As a starting point, I wanted to try imaging a copy of someone's internal SD card onto an external SD of mine (I have a 4gb card, and the internal SD chip is 4gb - yep, I tore it apart too). Maybe the tablet will choose to boot from the SD instead, or at least bootstrap it to a point where I can Fastboot it or something.

Anyone willing to post their mmcblk0.img...?
[Android Q&A, Help & Troubleshooting] Gigaah:
I'm not very well versed in these matters. I've been trying to dig up some sort of information on what to do with the vtab1008. I stumbled upon The "one laptop for every child" project. Low and behold. In addition to the XO-1.75 running very similar hardware. They have a Tablet called the XO-3. Same dimensions and appears to be AT LEAST a direct relative to the VTAB1008. They have signed roms for it. Source code.EC Firmware(Boot loaders/Recover?) You have to dig around a bit. I have not tried to do anything with any of it. I'm just not really familiar enough with how things work.

From the perspective of a newb dumbo like me it seems getting this information into the right hands would almost certainly get something moving and generate some interest from coders and generally people who know what the hell to do with this stuff.

I did notice as well in december there was an update to the EC firmware that closed some some loopholes. Funny that the update that put the brakes on our rooting happened right about then huh?

wiki.laptop.org/go/Vizio_VTAB1008

The files labeled Q5XXX are for the XO-3

The site no longer has signed rom files for anything under Q5A03. which is where I think the Firmware was changed to close up loopholes.

Here is a change long of the project and code.

code.coreboot.org/p/openfirmware/timeline/all/?_px_sk=creation_dtime&_px_so=a&_px_p=31

Link to the XO-3 portion of the project.It has hyperlinks to the firmware

wiki.laptop.org/go/XO-3

Firmware Section.

wiki.laptop.org/go/Firmware

Boot Sequence Info

wiki.laptop.org/go/Category:XO_startup

You have to dig but there is a wealth of information about flashing and recovery and security etc.I hope this can help someone.If the information is as closely related as I'd like to think it is. It could maybe turn the vtab into a very awsome project for the people who actually have skills in these matters.

I did have a look at the xo-3 stuff, but to me this looks like it is no help at all, it depends on in software built in flashing methods that we do not have on the vtab firmware. Also the device seems to be doa meaning it was discontinued before release, there are two firmwares available for it, but i doubt they are anywhere near usable.

Hello there,

I'm currently attempting chingchongpingpong's Star Trek LCARS project *I can't link yet otherwise I'd give one*

I am using Phiremod 7.1, which I used after using CW and the manualNooter to to root my 1.2 Nook Color. I have Desktop Visualizer and ADW EX.

The assistance I'm looking for here is related to that I'm having trouble navigating as well as issues with functions not working. To follow the project you have to create widgets through DV and use images for the icons, fair enough but when I did get icons created when I do get them placed properly they don't align with the project background and I when I go into edit it's basically impossible to get the image to line up and the re-sizing thing increases the area for the widget and it's just getting so darn frustrating It's driving me nuts.

*edit* I solved a few problems but I can't seem to resize with desktop visualizer in the way I need them. :(

[Samsung Galaxy Nexus] mohitrocks:
Hey Everyone,

I currently have a Galaxy Nexus pre-ordered on Bell on a three year contract ($185 and $50/month for 500mb of data + 150 minutes). I found out that Mobilicity is also a GSM network that will work with the Galaxy Nexus and the price per month is only $17.50/month (for unlimited data, unlimited local calling and caller ID!) but the only downside is that many people report that the network drops often and there is no HSPA+ speeds. I know this may seem like a REALLY stupid question to ask, but do you guys think I should cancel the order, and then re-order the Galaxy Nexus unlocked for $800? (Taxes + cancellation fee). I mean with the network not supporting HSPA+ and the network itself not being supported in some areas in Canada (although I don't travel much and according to the coverage map I'm fully supported), is it really worth it from switching from my current order with Bell on a 3 year contract to Mobilicity?

Note: I realize its a fairly stupid question, but I haven't been thinking straight for the past few days and your comments will be extremely appreciated.
[Samsung Galaxy Nexus] Taggard:
I go through 500MB of data in a week. That plan would never work for me. I have a T-Moble/Wal-Mart $30/month unlimited data (5GB at H+), unlimited text, 100 talk mins (I never talk on the phone) and bought an unlocked GN for $850. The closest plan would cost me $99/month with Verizon.

I don't get why people can't realize that buying a good phone and then getting a cheap plan is cheaper in the long run.
[Samsung Galaxy Nexus] Towle:
I pay $60 after taxes and fees per month on Tmobile USA with 1000 minutes, unlimited texts, and 5GB of H+ speeds. I got the Galaxy S II for $149 with a 2 year contract. Over 2 years I will pay a total of about $1400 after all taxes and fees, including the price of the phone. Over 2 years you will pay about $1,600 including the price of your phone... Who's saving money?
[Samsung Galaxy Nexus] martonikaj:
Huh?

$30 x 24mo + $850 phone = $1570

$60 x 24mo + $150 phone = $1590

And he overpaid for the phone considering most are getting it for around ~$700 shipped. So for most in his situation it'd be more like ~$1420 for 2 years + phone. And you got a good deal on your SGSII, as T-mo advertises it for $229. So we can say most people's annual cost in your situation is ~$1670.

So if we go with real-world math its ~$1420 vs. ~$1670....

Not to mention that you're on a contract, and he isn't. Some people don't like being in a contract and that's worth it for them.
